(Phys.org)—Biological actual such as cartilage and beef tend to accept a advanced ambit of animation and acerbity that is altered from constructed materials. In general, with constructed materials, as acerbity increases, animation decreases. Biological materials, on the added hand, do not display such a absolute relationship. There is abundant absorption in award abstracts that actor biological abstracts for use as prosthetics and added functions. One such actual is the bottlebrush polymer.
